The 9529AB Series terminal balancing valve by Red-White Valve Corp. is a high-performance, lead-free brass ON/OFF valve engineered for hydronic balancing in closed-loop systems. This model is designed specifically with solder joint ends (ASME B16.22) to meet the rigorous demands of commercial and residential HVAC systems.
Key Features & Benefits
- Precision Flow Control: Integrated ON/OFF functionality with a regulating scale allows for accurate terminal balancing, ensuring optimal performance in hydronic distribution systems.
- Solder Joint Connections: Built for secure and durable installation, the 9529AB features solder joint ends conforming to ASME B16.22 standards for seamless integration with copper piping.
- Certified Lead-Free: Compliant with AB1953, NSF/ANSI 61, and NSF/ANSI 372, the valve is manufactured using lead-free brass (C27450/C28000), making it safe for use in potable water applications.
- Test Point Integration: Includes factory-mounted test points with EPDM Perox gaskets, enabling simplified differential pressure and flow measurements.
- Actuator-Ready: Threaded M30x1.5 bonnet allows for optional linear actuator installation post-deployment — compatible with RWV Vaurien actuator series.
- Durable Construction: Built from premium components including stainless steel stems and springs, brass cartridges, and reinforced polyamide control caps, offering long service life under demanding conditions.
- Thermal Operating Range: Operates reliably in temperatures ranging from 15°F to 260°F, with appropriate fluid additives for subfreezing or high-temperature conditions.
- High Pressure Rating: Rated for 300 WOG (max 300 psi at 160°F, 150 psi at 260°F), ensuring safety in high-pressure environments.
